Product details

Page size note — 264 vs 256 bytes

This chip uses 264-byte pages, not the 256-byte pages found in the AT45DB021E-SHN2B-T variant. If your firmware's SPI driver assumes 256-byte boundaries (common in generic SPI Flash libraries), you will need to adjust the page-write routine. The extra 8 bytes per page are available as a scratchpad or ECC area if the controller supports it.

Lifecycle and sourcing

Listed as Active with ROHS3 compliance. No end-of-life notice on record, so it is safe to qualify for new production. Sourced through independent distribution; availability and current pricing are confirmed at quote time against an RFQ.

Frequently asked questions

Is AT45DB021E-SSHN-T a direct replacement for AT45DB021D?

The AT45DB021E is the newer generation and is generally a drop-in replacement for the AT45DB021D in the same 8-SOIC package, but verify the page organization (264 bytes vs 256 bytes) and any minor timing differences in your specific application.

Where can I buy AT45DB021E-SSHN-T?

This part is sourced to order through independent distribution. Submit an RFQ for current availability and pricing.

Does AT45DB021E-SSHN-T come in tape and reel packaging?

Yes, it is available in Tape & Reel (TR) and Cut Tape (CT) options.

Is AT45DB021E-SSHN-T RoHS compliant?
